For more than 60 years, the Lawrence Livermore National Laboratory (LLNL) has applied science and technology to make the world a safer place.

We have openings for computational physicists to pursue challenges relevant to national security in the development of multi-physics simulation codes. You will collaborate as part of an interdisciplinary code development team in advancing the state of the art in large-scale multi- physics simulation. The national security mission involves developing simulation capabilities for Stockpile Stewardship, nuclear counter-terrorism, conventional weapons, and high energy density physics experiments. The code development focus is on models and algorithms for use in high-performance computing on the latest large-scale parallel computing platforms. This position is in the Design Physics Division within the Weapons and Complex Integration (WCI) Directorate.

Essential Duties

- Develop, release, and maintain models and algorithms using advanced simulation tools to support the physics capabilities based on requirements from a diverse user community. - Provide technical support, informal training, and guidance to code users in the application of simulation tools developed. - Participate in the development of simulation tools as part of a multi-disciplinary team. - Present and disseminate research results at scientific conferences and in peer-reviewed publications, in both open and classified environments, internal and external to LLNL. - Perform other duties as assigned.

Qualifications

- PhD in physics, mathematics, engineering, or related field or the equivalent combination of education and related experience. - Demonstrated technical mastery in one or more science disciplines, such as shock hydrodynamics, fluid mechanics, material behavior, particle transport, radiation transport, plasma physics or chemical processes.

- Experience developing, implementing and evaluating algorithms and methods for their fitness for a particular task, as well as developing and implementing new numerical algorithms. - Experience in converting theory into models or algorithms appropriate for numerical simulation.

Pre-Employment Drug Test: External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.

Security Clearance: This position requires a Department of Energy (DOE) Q-level clearance.

If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing. Q-level clearance requires U.S. citizenship. If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.

Note: This is a Career Indefinite position. Lab employees and external candidates may be considered for this position.
